I put an intra-Africa award on hold with DL miles at 60,000 miles in Y. I think Ive read elsewhere that NW offers cheaper intra-Africa awards, is that true?

And for those of you who have completed your trips, can you tell us about Kenya Airways and Air Seychelles service on any of these flights? I have CDG-SEZ in J class booked, but am not expecting much (although AF isnt that great either besides their comfortable, lie-flat seat)
